Oracle OpenWorld 2013 - Systems Keynote
I'd like to recommend watching the following Oracle OpenWorld 2013 Keynote, specially from the middle when John Fowler speaks: Kurian and Fowler -- Oracle OpenWorld Keynote 9-24-2013
Among others, Solaris 11is handling 3072 threads and 32 TB RAM.
That's absolutely not ordinary out there, but normal for Solaris 11.
Regards.
